Figure 1 Kaplan-Meier survival analysis of troponin-positive and -negative patients. (A) The overall 30-day mortality was significantly higher in troponin-positive (n = 32) than in troponin-negative (n = 26) patients (p = 0.018). (B) When subgroups of patients with volume-refractory shock needing catecholamine therapy (n = 24) and patients without shock (n = 34) were analyzed separately, a significant difference in mortality was found in the subgroup without shock only (p = 0.03). ns = not significant.
